cooling fan installation
The included Novak 30x30x6mm clear cooling fan (Novak kit #5648) is
required for the Goat 3S when using a 3-cell Li-Po pack. In addition, the
fan comes with the connector already on it to match the pins on the Goat 3S.
The Goat 3S ESC features a set of power output pins for running auxiliary cooling
fans, so you can add fans to the motor, the ESC or both, and they will switch on
and off with the ESC’s power switch. These pins output 6.0 VDC (same as the
BEC), so you will get maximum output from cooling fans without over powering
them by running directly from the battery pack’s voltage.
The pin-out label located on the
front lower section of the ESC’s
case (under the pins, push button,
& LEDs) shows the polarity of the
power output pins.
The 2 power output pins are
on the left front edge of the PC
board--Positive (+) is on the left,
and Negative (–) is on the right.
The 3 pins behind them are for
the user-replaceable input signal
harness--Polarity of these is the
same: Positive in the middle,
Negative on the right, and input
signal is the extra pin on the left.
sensor harness wiring
Should any of the 26G Teflon wires pull out of the connector on the end
of the motor’s sensor harness, re-insert them in the appropriate slot in the
connector as shown below. There is a small plastic tab that grabs a small
raised barb on the back of the metal socket crimped onto the Teflon wire’s
end. The plastic tab should be checked to make sure it has not deformed
excessively before inserting the metal socket into the plastic connector
housing with the barb toward to plastic tabs.
If the motor’s
sensor harness
gets damaged,
please contact

step
Mount the speed control so that the power wires are as far away from other electronics
as possible. Make sure that the speed control or the power wires will not interfere with
any moving parts in the vehicle. Select a location that has good cooling and allows
airflow through heat sinks.
If the ESC gets air flow, it will run cooler; and that means it will be more efficient!

Synthesized FM Receiver: 75 Mhz.
1. INSTALL 3S Li-Po EQUIPMENT (if using 2S Li-Po, skip to 2)
If using a 3S Li-Po or 9-cell Ni-MH battery pack, the included external BEC module
(Novak #5463) and cooling fan (Novak #5648) must be installed. Refer to STEP 2A
below and COOLING FAN INSTALLATION on page 4 for installation instructions.
2. MOUNT SPEED CONTROL IN VEHICLE
Use the included double-sided tape to mount the speed control in vehicle (do not use
glue). Avoid contact with side walls or other chassis components to avoid vibration damage.
Be sure receiver & antenna are mounted as far from ESC, power wires, battery, &
servo as possible--these components all emit RF noise when throttle is applied. On
graphite or aluminum chassis vehicles, it may help to place receiver on edge with
crystal & antenna as far above chassis as possible.
Note: Mount antenna as close to receiver as possible--trail any excess wire off top of
antenna mast (cutting or coiling excess antenna wire will reduce radio range).
3. SECURE POWER TRANS-CAP MODULE TO CHASSIS
Use included double-sided tape, or a tie-wrap, to mount Power Trans-Cap Module to
the vehicle’s chassis or shock tower. Module can also be tie-wrapped along the power
wires--this requires less space on the chassis and provides good isolation from vibration.
4. INSTALL ON/OFF SWITCH
Use a screw or the included double-sided tape, and mount the switch where it
will be easy to access--be sure to select a position where it will not get damaged
or get switched OFF during a crash or roll-over.

Bec installation
–
(Fig. 5)
The included Novak external BEC module is required for the Goat 3S
when using a 3S Li-Po/9 Ni-MH batteries. This external BEC supplies
power to the receiver and servos; the internal BEC supplies power to the
ESC and fan.
1. MOUNT EXTERNAL BEC IN VEHICLE
Use the included tie-wraps or double-sided tape to mount the BEC and
the ON/OFF switch on your chassis, close to the main battery pack.
2. SOLDER WIRES TO MAIN POWER SOURCE
Solder red (positive) wire of BEC to ESC’s positive power wire tab. Solder
black (negative) wire of BEC to ESC’s negative power wire tab. Shorten
red and black BEC wires, if possible.
3. PLUG THE BEC INTO THE RECEIVER
Plug the BEC’s 3-pin JST connector into the receiver’s battery slot, making
sure the polarity is correct. On most receivers, the black wire will face toward
the outside of the receiver, and the red will face the center of the receiver.
4. REMOVE RED WIRE FROM ESC’S INPUT HARNESS
Remove the red wire from the connector on the ESC’s input signal harness.
Insulate the red wire to avoid short-circuiting; the wire is live.
Damage will occur if red wire is not disconnected and will void warranty!
5. EXTERNAL BEC OPERATION
Once installed, first, turn on BEC’s power switch, and then turn on ESC’s power
switch. The BEC will be providing power for only the servos and receiver, NOT
the ESC. When turning off the radio system, turn ESC off first, then BEC.
a.
When the BEC is switched ON, the blue light will turn on.
NOTE: Double check that your battery pack is fully charged before operating the BEC.
You will NOT have radio control of BEC if the main battery fails or is fully discharged.

1. SOLDER MOTOR POWER WIRES TO MOTOR
a. Cut the BLUE, YELLOW, & ORANGE silicone motor power wires to the
desired length, and strip 1/8-3/16” of insulation from the end of each
wire. Tightly twist the exposed strands of wire, and tin the exposed
end section of each wire with solder with a good, high heat iron.
b. Solder the ESC’s BLUE Phase ‘A’ motor wire to the motor’s phase ‘A’
solder tab. Apply heat to exposed wire with soldering iron, and add
solder to the tip of the iron & the wire--Add just enough solder to
form a clean & continuous joint from the solder tab up onto the wire.
IMPORTANT NOTE: DO NOT OVERHEAT SOLDER TABS
Prolonged/excessive heating of solder tabs (motor or ESC) will
cause damage.
c. Solder the ESC’s YELLOW Phase ‘B’ motor wire to the motor’s phase
‘B’ solder tab as described in Step 5B above.
d. Solder the ESC’s ORANGE Phase ‘C’ motor wire to the motor’s phase
‘C’ solder tab as described in Step 5B above.
NOTE: Make sure no wire strands have strayed to an adjacent
solder tab, this will result in short-circuiting & severe ESC damage,
which will void the warranty.
2. CONNECT MOTOR’S SENSOR HARNESS TO ESC
Insert the 6-pin connector on the end of the motor’s Teflon sensor wires
into ESC’s sensor harness socket--the connector is keyed and will only
go together in one direction. Use Novak Brushless Extension Harnesses
(Novak #S5357 & #S5358), if necessary.

The Goat 3S ESC automatically switches to Brush-Mode when the ESC’s power
is switched ON and no brushless motor sensor harness is connected.
2. MOTOR CAPACITORS
Electric brush-type motors generate RF noise that causes interference. Novak’s
0.1µF (50V) non-polarized, ceramic capacitors (Novak #5620) must be used on
all brushed motors to reduce motor noise & prevent ESC damage.
Note: Some motors come with built-in capacitors. If your motor only has 2 capacitors, you
need to install a capacitor between the positive & negative motor tabs––If you experience radio

To connect the Goat 3S to the battery pack using connectors, we suggest low-loss,
high power connectors like Novak’s Power Connectors (Novak #5731) or Dean’s Ultra.
• Use polarized connectors.
• Use a female connector on battery packs to avoid shorting.
Reverse voltage will damage ESC & void warranty.
1. INSTALL BATTERY CONNECTOR
a. Cut the RED & BLACK silicone battery power wire to the desired length, and
strip 1/8”–3/16” of insulation from the end of each wire. Tightly twist and tin
the ends of the exposed wire with solder.
b. Solder the ESC’s RED (+) battery wire to the connector’s POSITIVE (+) contact.
c. Solder the ESC’s BLACK (–) battery wire to the connector’s NEGATIVE (–) contact.
D. Cover the exposed solder joints with heat shrink tubing to prevent possible short circuits.
2. CONNECT ESC TO BATTERY PACK
Connect the speed control’s battery connector to a fully charged 2-3 Li-Po cells
or 4-9 Ni-MH cells (1.2 VDC/cell) battery pack.
NOTE: If using Ni-MH batteries, the Li-Po Cut-Off Circuitry must be deactivated (page 6).
